Abstract

Aim to demand for automobile covering parts of measurement, this paper puts forward a new kind of optical inspection method, which combines photography with dense point scanning measurement. In order to meet the requirement of measuring the covering parts of automobiles, this paper proposes a new kind of optical inspection method which combines photography with dense points scanning measurement. The photogrammetry is used for landmark coordinates measurement, dense point clouds are gathered by scanning measuring equipment, According to the distance between the landmark invariance, a serial of point clouds are coarse registered with public landmark, a improved ICP method is used to promote the accuracy of registration, Experiments show that ultimately discrete points model can realize optical measurement for automobile covering parts, measurement accuracy in the range of 0.1 mm, it is satisfied the requirement of rapid optical measurement for automobile covering parts.
